Question: A stone is thrown vertically upward with a speed of 24.0m/s.

a) how fast is it moving when it is at a height of 13.0m? I got 17.9 m/s

b) How much time is required to reach this height? I got 4.28s and 6.20s

c) Why are there two answers to b? I said because the stone reaches the given hieght two time, on the way up and then again on the way down
